Evaluation of Crystallization Behavior of PP/HDPE Blend via Changing Melt Flow Index

The dependence of properties on the structure and morphology of semicrystalline polymers offers an effective way to tailor the properties of these materials through crystal engineering.To control structure and morphology of semicrystalline polymer blends, and therefore their physical and mechanicalproperties, a full understanding of their crystallization behaviour is essential [1]. The objective of this article is to investigate the influence of melt flow index (MFI) on thecrystallization behaviour of polypropylene/high density polyethylene (PP/HDPE) blend. For this purpose, three HDPEs with different MFI were selected and blended with PP.
